CANTILEVER SHELVING SYSTEM

Description

FIELD

[0001] The present disclosure relates to cantilever shelving systems and storage rack assemblies.

BACKGROUND

[0002] This section provides background information related to the present disclosure which is not necessarily prior art.

[0003] Cantilever shelving systems and storage rack assemblies are readily adaptable for supporting and storing a variety of items and have found widespread use in industrial, commercial and residential applications.

[0004] Many existing cantilever shelving systems and storage rack assemblies include frames and shelves having fixed dimensions in well-known standard sizes which cannot be adapted or modified to accommodate various and changing customer requirements. Further, known shelving units do not readily accommodate integration with standard-sized industrial and/or commercial equipment with which the shelving system may be associated during use. Consequently, these shelving systems and storage rack assemblies offer limited flexibility in configuration and use.

[0005] Examples of cantilever shelving systems can be found in patent publications WO 2013/071977 A1, WO 03/088782 A2 and DE 202 15 552 U1.

DETAILED DESCRIPTION

[0016] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0017] An exemplary cantilever shelving system 1 according to the principles of the present disclosure is shown and understood with reference to FIGs. 1-11. The cantilever shelving system 1 of the present disclosure can provide multiple, vertically-arranged and horizontally-oriented load-bearing platforms for supporting and/or storing items in a workspace or storage area. The cantilever shelving system 1 of the present disclosure can be easily adapted or modified to accommodate various and changing user requirements, and can readily accommodate operable integration with standard-sized industrial and/or commercial equipment with which the shelving system may be associated during use.

[0018] With reference to the figures, the cantilever shelving system 1 of the present disclosure can generally include a frame structure 10, a cantilever shelf support structure 12, and a plurality of load-bearing shelves 14 that can be supported by the cantilever shelf support structure 12 and the frame structure 10.

[0019] The frame structure 10 can generally include at least two vertically-oriented or upright support members 16, a lateral support structure 18 interconnecting the upright support members 16, and a base 20.

[0020] Referring to FIGs. 1, 2, and 9, each of the upright support members or vertical support posts 16 can extend vertically along a longitudinal axis X. In one aspect of the present disclosure, the vertical support posts 16 can incorporate a tubular construction or bar extending along the longitudinal axis X and having an exterior surface. In another aspect, a tubular construction can take the form of a hollow, metal tube having a rectangular cross-section having a front side 22, a back side 24, and opposing lateral sides 26. It can be appreciated, however, that other materials and cross-sectional geometries are contemplated within the scope of the present disclosure. Each vertical support post 16 can include an end cap 28 covering each longitudinal end of the vertical support posts 16.

[0021] At least two vertical support posts 16 can be positioned from one another in a laterally spaced-apart relationship along a lateral axis Y to establish a width dimension W of the cantilever shelving system 1. As shown in the exemplary embodiment of the cantilever shelving system 1 of the present disclosure of FIG. 1, the cantilever shelving system 1 can include three vertical support posts 16 positioned in a laterally spaced-apart manner and equidistant from one another. However, it can be understood and appreciated, that a cantilever shelving system 1 according to the principles of the present disclosure can be constructed to any desired width dimension W and include any number of vertical support posts 16 (of at least two or more). Further, the vertical support posts 16 can be laterally space-apart equal or unequal distances, depending on the uses or requirements of the cantilever shelving system 1.

[0022] As illustrated in FIGs. 1 and 5, each of the vertical support posts 16 can include a plurality of spaced-apart, support members or hanger pins 30 that can protrude or extend outwardly from one or both of the opposing lateral sides 26 of the vertical support posts 16. The hanger pins 30 can be positioned at a plurality of discrete vertical locations in a direction along the longitudinal axis X of the vertical support post 16. The hanger pins 30 can be integrally formed with or fixedly attached to the vertical support posts 16, such as by molding, extruding, forming, mechanical fastening (e.g., threading, interference or deforming), welding, or the like. In one aspect, the hanger pins 30 can exhibit a generally circular, solid cross-section, although cross-sections of other geometries and hollow cross-sections are also contemplated. The hanger pins 30 can protrude from the opposing lateral sides 26 of the vertical support posts 16 so as to be operable to engage the cantilever shelf support structure 12 as will be discussed further herein.

[0023] Turning again to FIG. 1, two or more of the vertical support posts 16 can be interconnected to one another by the lateral support structure 18. The lateral support structure 18 can include one or more horizontal crossbars 32. In one aspect of the present disclosure, the horizontal crossbars 32 can have a tubular or bar construction extending along a longitudinal axis and having an exterior surface. In another aspect, a tubular construction can take the form of a hollow, metal tube having a rectangular cross-section having a front side, a back side, and opposing upper and lower sides. It can be appreciated, however, that other materials and cross-sectional geometries are contemplated within the scope of the present disclosure. Each horizontal crossbar 32 can include an end cap (not shown) covering each longitudinal end of the horizontal crossbar 32.

[0024] Additionally, or alternatively, the lateral support structure 18 can include one or more cross-braces 36. In one aspect of the present disclosure, the cross-braces 36 can have a stamped, metal construction. However, other materials and configurations are contemplated within the scope of the present disclosure.

[0025] The horizontal crossbars 32 can be sized to extend between and/or across some or all of the vertical support posts 16 of the frame structure 10 to laterally interconnect two or more of the vertical support posts 16 together. For example, in one aspect, a horizontal crossbar 32 can be sized to extend between and interconnect two adjacent vertical support posts 16 of the frame structure 10. Alternatively, or in addition, a horizontal crossbar 32 can be sized to extend across and interconnect all of the vertical support posts 16 in the frame structure 10, i.e., across the entire width W of the cantilever shelving system 1. In still another alternative or additional arrangement, a horizontal crossbar 32 can be sized to extend across more than two vertical support posts 16, but less than the entire width W of the shelving system. The horizontal crossbars 32 can be joined or connected to the respective vertical support posts 16 in any of a variety of ways, such as by threaded or deformable fasteners, welding or other similar means.

[0026] One or more horizontal crossbars 32 can be positioned at one or more vertical locations along the longitudinal axes X of the vertical support posts 16. In one aspect of the disclosure the cantilever shelving system 1, one or more horizontal crossbars 32 can be included near the upper ends 38 of the vertical support posts 16 and/or a one or more horizontal crossbars 32 can be included near the lower ends 40 of the vertical support posts 16, as shown in FIGs. 1 and 3, for example.

[0027] Also as shown in the embodiments of FIGs. 1 and 9, in addition to the one or more horizontal crossbars 32, the lateral support structure of the cantilever shelving system 1 can include one or more cross-braces 36. The cross-braces 36 can include a pair of flat, stamped metal slats or bars 42 arranged in a criss-crossed relationship and fastened or joined to one another at approximately their respective midpoints, such as in a "X" pattern.

[0028] The cantilever shelving system 1 can include cross-braces 36 between each of the adjacent pairs of vertical support posts 16, as shown in the figures. As with the horizontal cross bars 32, the cross-braces 36 can be sized to extend between and interconnect two adjacent vertical support posts 16, or some or all of the vertical support posts 16 included in the cantilever shelving system 1. The cross-braces 36 can be joined or connected to the respective vertical support posts 16 in any of a variety of ways, such as by threaded or deformable fasteners, welding or other similar means.

[0029] Referring to FIGs. 1, 3 and 4, the frame structure can also include a base 20. The base 20 can include a plurality base supports 44 and one or more base shelves 46.

[0030] Each base support 44 can be associated with and can be attached to a corresponding a vertical support post 16. Therefore, the base 20 of the frame structure 10 can include at least two base supports 44 that can each be associated with the vertical support posts 16 located at opposite lateral ends of the cantilever shelving system 1. Every vertical support post 16, however, may not have a corresponding base support 44 attached thereto. For example, if three vertical support posts 16 are included in the frame structure 10, there may not be a base support 44 attached the vertical support post 16 intermediate the opposite lateral ends of the cantilever shelving system 1.

[0031] The base support 44 can include a horizontal support leg 48 which can have a tubular or bar construction having an exterior surface. In another aspect, the tubular construction can take the form of a hollow, metal tube having a rectangular cross-section having an upper side 50, a lower side 52, and opposing lateral sides 54. It can be appreciated, however, that other materials and cross-sectional geometries are contemplated within the scope of the present disclosure. In one aspect of the present disclosure, the horizontal support legs 48 of the base supports 44 can all have the same cross-sectional dimensions. In another aspect of the disclosure, a horizontal support leg 48 of at least one base support 44 can have cross-sectional dimension(s) resulting in a different cross-section than the other horizontal support legs 48 of other base supports 44.

[0032] The horizontal support leg 48 can extend along a longitudinal axis Z from a proximal end 54 that is adjacent to the corresponding vertical support post 16 to which it attached, toward a distal or terminal end 56. The horizontal support leg 48 can extend forward from the front side 22 of the corresponding vertical support post 16 such that the horizontal support leg 48 can form an angle of approximately ninety degrees with the vertical support post 16. The terminal end 56 of each horizontal support leg 48 can include an end cap 58.

[0033] The horizontal support leg 48 can be attached or connected to a respective vertical support post 16 at its proximal end 54, such as by threaded or deformable fasteners, welding or other means. For example, a flange 60 can be integral with or affixed to (e.g., such as by welding) the proximal end 54 of the horizontal support leg 48. The flange 60 can extend along the front side 22 of the vertical support post 16 above and below the horizontal support leg 48. The flange 60 can include mounting apertures 62. The mounting apertures 62 can accommodate fasteners 64 which can engage the vertical support post 16 to fixedly attach the horizontal support leg 48 to the vertical support post 16. In addition, or alternatively, a mounting strap 66 can be fixedly attached to the lateral sides 54 of the horizontal support leg 48 at the proximal end 54 of the horizontal support leg 48 and extend to the lateral side(s) 26 of the vertical support post 16 to also secure the horizontal support leg 48 to the vertical support post 16.

[0034] As shown in FIG. 3, the base support 44 can also include a support foot 68 located at or near the distal end 56 of the horizontal support leg 48. The support foot 68 can extend generally vertically downwardly from the horizontal support leg 48. The support foot 68 can be adjustable in length. For example, the support foot 68 can include a leveler, such as a bolt leveler 72.

[0035] The base support 44 can be attached to the vertical support post 16 at or near a lower vertical end of the vertical support post 16. Thus, the base support 44 and the lower end of the vertical support post 16 can cooperate to provide a stable foundation for the cantilever shelving system 1 on the support surface 70 (e.g., a floor) upon which the cantilever shelving system 1 is positioned for use. In one aspect of the disclosure, all of the base supports 44 can be positioned and attached to the vertical support posts 16 at the same vertical height H1, such as shown in FIG. 1. In this configuration, the upper sides 50 of all the horizontal support legs 48 can all be situated in a common i.e., first, horizontal plane YZ1. For example, the base supports 44 can be positioned on the vertical support post 16 such that the upper sides 50 of the horizontal support legs 48 are about 15,24 to 25,4 centimetres (6 to 10 inches) above the support surface 70.

[0036] In another aspect of the disclosure, as illustrated in FIGs. 4, 9 and 11, at least one base support 44' can be positioned on the vertical support post 16 at a vertical height H2 different than other base supports 44. In such a configuration, the upper side 50' of the horizontal support leg 48' of the one base support 44' lies in a different, i.e., second, horizontal plane YZ2. For example, the second horizontal plane H2 can be vertically lower than the first horizontal plane H1. With reference to FIGs. 4 and 9, an exemplary low-profile base support 44' is shown. The low-profile base support 44' can be positioned on the vertical support post 16 such that the upper side 50' of its horizontal support leg 48' is about 7,62 to 12,7 centimetres (3 to 5 inches) above the support surface 70.

[0037] With reference to FIGs. 12 and 13, an alternative embodiment of a base support 44" is shown. As illustrated in FIGs. 12 and 13, the base support 44" includes both a mounting strap 66" and a mounting bracket 67" which can be securely connected to the vertical support post 16 by fasteners 64" passing mounting through apertures 62" in the mounting bracket 67".

[0038] One or more base shelves 46 can also be included in the base 20. A base shelf 46 can be positioned on or between adjacent base supports 44. Alternatively, a base shelf 46 can span more than two base supports 44. The base shelf 46 can be fixedly attached to two or more of the base supports 44. In addition to providing a lower storage space for the cantilever shelving system 1, the one or more base shelves 46 can add to the rigidity of the base 20 and the frame structure 10 when securely fastened to the base supports 44.

[0039] The base shelf 46 can include a construction of cross members 74 fixedly connected to one another, such as in a rectangular framework. A support surface 76 can be attached to an upper side of the framework. In one aspect, the support surface 76 can include a wire rack. In other aspects, the support surface can include a panel.

[0040] Referring to FIGs. 5-8, the cantilever shelf support structure 12 of the cantilever shelving system 1 of the present disclosure can be understood. The cantilever shelf support structure 12 can include a plurality of horizontally extending cantilever support arms 78. As best shown in FIG. 6, an exemplary cantilever support arm 78 can comprise an elongated downwardly open channel having a planar upper wall 80 and opposing planar side walls 82. The cantilever support arms 78 can extend from a proximal end 84 to a distal end 86 along a longitudinal axis Z2. The side walls 82 of the cantilever support arms 78 can be tapered, narrowing from the proximal end 84 to the distal end 86.

[0041] A mounting flange 88 can be integrally formed with or attached to the proximal end 84 of the cantilever support arm 78. The mounting flange 88 can include opposing side braces 90 that are spaced laterally apart to enable the mounting flange 88 to closely fit on, over or around the opposing lateral sides 26 of a vertical support post 16. Each of the side braces 90 can include at least a first open slot 92 extending to a rear end 94 of the mounting flange 88. The first open slot 92 can terminate in an offset portion 96. Additionally, each of the side braces 90 can also include a second open slot 98 having a terminal end 100. The second open slot 98 can be offset from the first open slot 92. In one aspect, the second open slot 98 is vertically aligned with and positioned below the offset portion 96 of the first open slot 92. The first and second open slots 92, 98 can be sized to accommodate and engage with the hanger pins 30 on the vertical support posts 16.

[0042] At least two elongated apertures or narrow slots 102 can be included in each of the side walls 82 of the cantilever support arm 78. At least one narrow slot 102 can be included near the proximal end 84 of the cantilever support arm 78, and at least one narrow slot 102 near the distal end 86 of the cantilever support arm 78. In one aspect, a pair of vertically extending and generally parallel narrow slots 102 can be included near each of the proximal and distal ends 84, 86 of each of the side walls 82 of the cantilever support arm 78, as shown in FIG. 6.

[0043] The cantilever shelf support structure 12 can also include a plurality of shelf support fittings 104. The shelf support fittings 104 can be adapted to attach to the cantilever support arms 78 by way of the narrow slots 102 in the side walls 82 of the cantilever support arms 78 as best seen in FIG. 5. Each shelf support fitting 104 can include a mounting portion 106 and a support portion 108. The mounting portion 106 can include at least one mounting tab 110 at an upper end and at least one lock notch 112 at a lower end. The mounting tab 110 can engage an inside surface of the side wall 82 of the cantilever support arm 78 above the narrow slot 102 and the lock notch 112 can engage a lower end of the narrow slot 102 when the shelf support fitting 104 is attached to the cantilever support arm 78.

[0044] The support portion 108 of the shelf support fitting 104 can be positioned adjacent to and offset from a lower end of the mounting portion 106. The support portion 104 can include an upward projection 114 at an outer end of the support portion 108 that is offset from the mounting portion 106 by a horizontal base 116. The projection 114 can be adapted to engage a load-bearing shelf 14.

[0045] FIGs. 1, 2, 5 and 8 show exemplary load bearing shelves 14 for use in the cantilever shelving system 1 of the present disclosure. The shelves 14 can be generally rectangular in shape and provide a load-bearing upper support structure or surface 118. The shelves 14 can include, for example, wire shelves and panel shelves well-known in the art having standard length dimensions, e.g., 60,96, 76,2, 91,44, 106,68, 121,92, 152,4,182,88 centimetres (24, 30, 36, 42, 48, 60 and 72 inches). Each shelf 14 can include a shelf mounting collar 120 at or near each of the four corners of the shelf 14. The shelf mounting collar 120 can be a generally hollow cylinder having an open lower end and a closed upper end. The shelf mounting collar 120 can engage the projection 114 and base 116 of the support portion 108 of the shelf support fitting 104 to attach the shelf 14 to the cantilever support arm 78. Suitable load-bearing shelves 14 that can be used in the cantilever shelving system 1 of the present disclosure are available from InterMetro Industries Corporation, the assignee of the present application, under the Super Erecta Shelf® product line.

[0046] The cantilever support arms 78 can be attached to the vertical support posts 16, as best illustrated in FIGs. 5 and 8. The mounting flange 88 of the cantilever support arm 78 can slide over lateral sides 26 of the vertical support post 16. The mounting flange 88 can slide horizontally past the hanger pins 30 which can then engage the first and second open slots 92, 98 in the braces 90 of the mounting flange 88. When the proximal end 84 of the cantilever support arm 78 abuts the front side 22 of the vertical support post 16, the cantilever support arm 78 and mounting flange 88 can slide vertically downwardly so that the hanger pins 30 can simultaneously engage or abut against the offset portion 96 of the first open slot 92 and the terminal end 100 of the second open slot 98. Thus, the cantilever support arm 78 is attached to the vertical support post 16 in a cantilevered manner.

[0047] A load-bearing shelf 14 as previously described can then be installed between two adjacent cantilever support arms 78. The shelf 14 can be lowered between the cantilever support arms 78 so that the shelf mounting collars 120 engage corresponding shelf support fittings 104 attached to the cantilever support arms 78. Thus, as illustrated in FIGs. 5 and 8, in the cantilever shelving system 1 of the present disclosure, the shelf 14 can be located adjacent to the cantilever support arm 78 and the end 124 of the shelf 14 does not overlap with the front side 22 of the vertical support post 16. As best shown in FIG. 8, the upper support surfaces 118 of the adjacent load-bearing shelves 14 can be coplanar. Moreover, the upper wall 80 of the cantilever support arm 78 is also coplanar with the support surfaces 118 of the adjacent shelves 14. Therefore, the cantilever support arm 78 of the cantilever shelving system 1 of the present disclosure can provide a continuous and smooth transition surface between adjacent shelves 14.

[0048] Referring again to FIGs. 1, 2 and 8, the cantilever shelving system 1 of the present disclosure, and particularly arrangement of the cantilever shelf supporting structure 12, can enable the width dimension W1 between adjacent portions of the frame structure 10, including the vertical support posts 16 and base supports 44, to be at least the same value as the length dimension of the shelf 14. For example, when a 91,44 centimetres (36 inches) shelf is installed in the cantilever shelving system 1 of the present disclosure, the width dimension W1 between the adjacent portions of the frame structure 10 can be at least 91,44 centimetres (36 inches). This feature is unlike prior known cantilever shelving systems. In prior known cantilever shelving systems, the width dimension between adjacent portions of the frame supporting a shelf is less than the length dimension of the shelf. This is because prior known supporting structure for mounting the shelf to the frame is located directly beneath the shelf or that structure forms part of the shelf, itself.

[0049] It can be appreciated that the cantilever shelving system 1 of the present disclosure provides significant advantages for adapting and/or modifying the cantilever shelving system 1 to accommodate various user requirements over known shelf systems. In addition, the cantilever shelving system 1 of the present disclosure can easily be operably integrated with standard industrial and/or commercial machinery or equipment with which the cantilever shelving system 1 may be associated during use.

[0050] For example, common commercial kitchen equipment 126 can have standard dimensions corresponding to the dimensions of known standard-sized shelves. In FIG. 2, a standard piece of kitchen equipment 126 is shown having a standard width dimension. The equipment 126 can be operably integrated with the cantilever shelving system 1 and located in the space created in the frame structure 10, between two of the vertical support posts 16 and corresponding base supports 44 and beneath the standard length shelves 14. As another example, a standard-wide piece of kitchen equipment 128 can be operably integrated with a cantilever shelving system 1 including a low-profile base support 44', as shown in FIGs. 9-11. The wide equipment 128 can, for example be moveable on casters 130 which can raise the base 132 of the equipment 128 about 10,16 to 15,24 centimetres (four to six inches) above the floor 70. The base 132 of the wide equipment 128 can pass over the low-profile base support 44' and can be located in the space created in the frame structure 10 between the vertical support posts 16 and corresponding base supports 44 and beneath the standard length shelves 14.

[0051] Additionally, it can also be appreciated from FIGs. 1, 2, and 9, that the cantilever shelving system 1 can incorporate a plurality of shelves 14, and the shelves 14 can have a plurality of different length and width dimensions. Further, it can be appreciated that the cantilever shelving system 1 can be constructed and/or modified (e.g., widened or narrowed) simply and easily by adding or removing portions of the frame structure 10 (e.g., vertical support posts 16 and base supports 44, 44').
